POCKET WElGHlNG-SCALE.

SPECIFICATION forming part of Letters Patent No. 379.746, dated March 20,1888.

Application filed September 15, 1887. Serial No. 249,746. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM R. WATT, of Somerville, in the county of Fayette and State of Tennessee, have invented a new and Im proved Pocket-Scale, of which the following is a full, clear, and exact description.

This invention relates to scales, the object of the invention being to provide a simple, cheap, and durable medicine-scale, and one wherein the parts are so constructed and arranged'that the beam and pan may be folded down so as to rest within a case of a size such that it may be easily put in the pocket of the owner.

Reference is to be had to the accompanying drawings, formin g apart of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the casein which my improved form'of scale is packed, the case being shown asit appears when closed. Fig. 2 is a plan view of the case, representing the same as it appears when open, the scale being shown as folded within the case. Fig. 3 is a front view of the case, the scale being represented as it appears when raised to a position for use, part of the case being broken away to disclose the connection between the scale-standard and a post that is secured to the bottom of the case; and Fig. 4 is an enlarged cross-sectional view taken on line as 00 of Fig. 3.

In the drawings above referred to, represents a case, one end of which is circular, and of a size such that it will readily receive a scale-pan, 11. The case 10 is provided with a cover, 12, which at one side is hinged to the main body of the case, a catch, 13, being provided at the opposite side of the case, so that when the cover is closed, as represented in Fig. 1, it may be securely locked to place.

To the bottom of the case 10 I secure a post, 14, and to this post I connect the scalestandard by means of a pin, 16, the lower end of the standard being slotted to provide for the entrance of the post 14, as is best shown in Figs. 2 and 3. To one side of the standard 15 I connect a bolt or catch, 17, which is secured to the standard by clips 2, the arrangement being such that when the standard is moved to the position in which it is shown in Fig. 3

the catch or bolt 17 may be moved downward, so as to bear against the outer face of the post 14, acting at this time to hold the standard against accidental displacement.

The upper end of the standard is slotted, as shown at 3, to receivethe scale-beam 18,which beam is mounted upon a pivot-pin, 19, and to one end of the beam 18 I pivot a rectangular block, 20, said block being supported by an outwardly-extending pin or bolt, 21, and it is to this block 20 that the pan 11 is secured.

In order that the pan may be held in a hori zontal position when the standard and the parts carried thereby are moved to the position in which they are shown in Fig. 3, I secure a spring, 22, to the under side of the beam 18, which spring extends outward beneath the block 20, bearing against said block and holding it in the position in which it is shown in the drawings last referred to; but when it is desired to fold the scale within its casea quarter-turn may be easily given to the pan to move it to the position in which it is shown in Fig. 2, the bolt or catch 17 at this time being withdrawn and the standard moved over in the direction of the arrow shown in Fig. 4.

Upon the beam, which is graduated in the usual well-known way, I mount a sliding weight, 24; and in order that the physician, apothecary, or other person having occasion to use this scale may havea handy implement to manipulate the material that is to be weighed or measured, I place a spatula, 30, within the case 10, said spatula being held against the rear side of the case by a post or pin, 6, as illustrated in Fig. 2.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a case, of a standard pivoted in the case, a scale-beam supported by the standard, and a pan pivoted on the end of the scale-beam and adapted to be turned at right angles thereto when the stand- 9 5 ard carrying the scale-beam is folded in the case, substantially as described.

2. The combination, with a case, of a scalestandard pivotally connected thereto, a beam supported by the standard, a pan, a block to which the pan is connected, a pin or bolt mounted upon a pin or bolt, 21, which exwhich extends outward from the beam and tends outward from the end of the standard, a passes through the block, and aspring carried I spring, 22, secured to the beam and arranged by the beam and arranged to bear against the to bear against the block, and a pan, 11, con
